This may seem like a dumb question but I just got a wireless mouse today and it works fine. The thing is I see no turn off for it. How do I turn this thing off so it is not running my batteries down when I am not using my computer? Currently I removed the batteries but this seems like a silly solution.

Most modern mice (including wireless) have a sleep feature that, instead of scanning every few milliseconds, they scan about once every 2 seconds, consuming less than 1 watt. At this rate, it would take a few months to drain the batteries, at which time the batteries would have lost a good portion of their capacity anyways.

In short, you shouldn't have to worry about turning the mouse off if it doesn't have a power switch/button, as it has an internal switch that does essentially the same thing.

In theory the mouse uses very little current until it detects rf from its receiver when the computer turns on.
The batteries always need to be in to maintain it's pairing identity with the receiver. Welcome to the world of waste! That's why I use a wired mouse. more eco freindly
